A simple assay...

Bioelectronic assays monitor in vitro cell health and behavior. Sensitive electrodes track cellular activity, while the culture remains undisturbed.



Noninvasively measure activity anytime, as often as needed, while cells remain in an optimally controlled environment.



Use basic cell culture techniques to perform quantitative assays that deliver high-resolution, functional data – with no need for dyes, labels, or complicated steps.



Measure with the push of a button or schedule recordings ahead of time. No incubation steps or complex handling required with a mostly hands-free assay.

Complex biology...

The versatility of the Maestro Pro makes it ideal for any lab. Monitor dynamic cellular activity and perform complex functional experiments with only basic cell culture.


Electrical Activity

Create detailed functional profiles of electrically active cells using microelectrode array (MEA) technology. Repeatedly measure from the same culture and track network development and activity.

  • Neurons
  • Cardiomyocytes
  • Skeletal muscles
  • Retinal cells
  • Primary or stem cells
  • 2D or 3D cultures

Cellular Kinetics

Monitor the health and behavior of any cell type using impedance-based technology. Bioelectrodes measure complex dynamic responses, capturing every minute to reveal detailed cellular kinetics.

  • Immuno-oncology
  • Cytotoxicity
  • Cell proliferation
  • Barrier function
  • Migration/invasion
  • Cell signaling



DISCOVERMaestro Pro multielectrode array system

The Maestro Pro

The latest technological advances to facilitate your research. The Maestro Pro features:

Dynamic responses

Detect key parameters of neural activity, network dynamics, and cardiac functionality, measure cell growth and cytolysis, barrier function, and signaling – all label-free and in real time.

Push-button acquisition

Simplify processes with Maestro’s automatically adjusted temperature and CO2 levels and integrated barcode scanner that conveniently tracks plate usage.

Precise cellular control

Recreate specific patterns of cellular activity using electrical stimulation or light pulses (with the Lumos™ optical stimulation system).

Integrated environment

Easily control temperature and CO2 levels while suppressing electrical noise and mechanical vibrations with Maestro’s smart environmental chamber. No need to take up incubator space.

High-throughput assay

Record from 6 up to 96 wells of MEA data, or 96 up to 384 wells of impedance data. The Maestro Pro is designed for the workload of busy labs.

On-the-go connectivity

Use the Impedance module to track changes in cell proliferation, viability, and cell death from any mobile device. No need to be in the lab.
